RAILROAD-RAIL. CHAIR.

SPECIFICATION forming part of Letters Patent No. 566,708, dated August25, 1896.

Application filed April 20, 18961 Serial No. 588,235. (No model.)

To @ZZ whomi t may concern:

Be it known that l, ROBERT O. BINGHAM, a citizen of the United States,residing at Sidney, in the county of Shelby and State of Ohio, haveinvented certain new and useful Improvements in Railroad-Rail Chairs,oi' which the following is a speciiication, reference being had thereinto the accompanying drawings.

illy invention relates to au improved railroad-rail chair made in twoparts or sections adapted to support and hold together the meeting endsof two railroad-rails, said chair comprising a main section and a cunealkeysection operating in a cuneal channel in the main section, lbothsections being provided with registering openings through which spikesmay be driven Ainto the cross-ties to hold the sections in properrelative position.

The invention will first be described in connection withtheacconipanying drawings, and then pointed out in the claims.

Figure 1 of the drawings is a perspective view showing two rails joinedtogether at their meeting ends by my improved chair, a portion ot' thekey-section being broken out to show the engagement of the lugs on themain section with the elongated holes in the web of the rail. Fig. 2 isa horizontal sectional view of the same on the line U,'Fig.l, a portionof the key-section being broken away to show one of the slots in thebaseoii' the main section, the broken-out portion being shown in dottedlines and the spikes omitted. Fig. 3 is a transverse sectional view onthe line y (y, Fig. 2. i is a like view illustrating the substitution ofbolts and nuts for the lugs shown in the other figures.

In the drawings, A A represent two railroad-rails, in the webs l ofwhich, near their meeting ends, are formed elongated holes 2, for apurpose hereinafter described.

3 is the tread of the rail, and i the base.

B is the main section of my improved railchair comprising a base Y),which underlies the ends ot' the rails and extends some distance on eachside of them,and a jaw 1)',shaped so as to overlie the tops of one sideof the bases of the rails and hear against the webs of the rails, theupper edge of the jaw resting against the under side of the caps ortreads of the rails, all as clearly seen in Figs. 3 and 4. In this sideof the base of the main section are formed notches 5 for the receptionof spikes. per side of the base o of the main section, opposite the jaw,is formed a cuneal channel (i, the outer wall 7 of which is of the saineheight as the inner wall; and in said base, near each end and inregister with the channel 6, is formed a slot S, for a purposehereinafter described.

C represents a key-section, comprising a flat cuneal plate c and anintegral jaw c', adapted to embrace the ends of the rails opposite thejaw b and in a precisely similar manner. The plate c of the key-sectionis of such thickness that when it is in place in the channel 6, whichextends some distance under the bases ot' the rails, its upper surfacewill lie flush with the upper surface of the base b of the niainsection, as clearly shown in the drawings, so that the upper surfaces ofthe bases of the two sections together forni the rail-seat, whereby theinner edge of the key-section will be irnily held in place by the rails.In the outer edge of plate c of the key-section, near each end, isformed a series of notches 9, through either of which, and through theslots 8 in the base Z9 of the main section, and into the tics T may bedriven spikes lO.

For the purpose of securing the` ends of the rails together, allowingonly for the natural expansion and contraction of the rails, I prefer toprovide the jaw b' of the main section with integral lateral lugs ll,adapted to enter the holes 2 in the webs l of the rails. By thisconstruction I dispense entirely with the use of bolts and nuts, anadvantage that will be at once apparent to those familiar with railroadconstruction. lf desired, however, the lugs may be dispensed with, andbolts l2 passed through both jaws and the rail-webs, as seen in Fig. e.

ln using my improved rail-chair the niain section is first placed on therails and then spiked to the cross-ties, after which the keysection isput in place, with its plate in the channel 6, and then driven forwardwith a wedging action until the parts are firmly secured together, whenthe two parts are spiked together and to the ties, as shown in Fig. 1.Should the key-section at any time become (Not shown.) In the upu IOO soloose as to be ineffective, the' spikes can be withdrawn and thekey-section driven farther forward until a proper tightness is secured,when the spikes may be again inserted through any of the notches.

lt will be seen that by my invention l have materially simpliiied theconstruction of railroad-rail chairs, in that l employ but two parts,and these are capable of being very easily and quickly assembled withthe rails.

Having thus described my invention, what l claim as new, and desire tosecure by Letters Patent, is-

l. A two-part railroad-rail chair comprising a main section of the fullwidth of the chair having a longitudinal cuneal channel and a verticalslot near each end in register with said channel, and a cunealkey-section adapted to operate in the channel in the main section andhaving a series of spike-receiving notches near each end in registerwith the slots in the main section, each of said sections having a jawadapted to bear against the respective sides of the rails.

2. A two-part railroad-rail chair comprising a main section of the fullwidth of the chair having a longitudinal cuneal channel and a verticalslot near each end in register with said channel, and a ounealkey-section adapted to operate in the channel in the main section andhavinga series of spike-receiving notches in its outer edge near eachend in register with the slots in the main section, each of saidsections having a jaw adapted to bear against they respective sides ofthe rails, the jaws of the main section being provided with iixed studsdesigned to enter holes formed in the ends of the rails.

3. A two-part railroad-rail chair comprising a main section of the fullwidth of the chair, but forming only a portion of the railseat, saidsection having a longitudinal cuneal channel in its base and a verticalslot near each end in register with said channel, and a cunealkey-section adapted to operate in the channel in the main section, theinner portion of its base lying iiush with the inner wall of the channeland thus completing the railseat, the outer portion of its base having4a series of spike-receiving notches formed therein near each end inregister with the slots in the main section, each of said sectionshaving a jaw adapted to bear against the respective sides of the rails.

ln testimony whereof l aiX my signature in presence of two witnesses.
